Best Motherboards for the Core i9 14900K
1. Gigabyte Z790 AORUS Pro X
E-ATX
Form Factor
1x Gen5 & 4x Gen4
PCI-E x4 Slots
1x Gen5 & 1x Gen4
PCI-E x16 Slots
DDR5 8266MHz
RAM Support
Gigabyte’s Z790 AORUS Pro X is a refreshed Z790 motherboard that is designed with Intel’s 14th generation in mind. However, it is still a Z790 motherboard, which means it also supports 13th-Gen and 12th-Gen CPUs. But what makes this particular Z790 board stand out is the all-white aesthetic, including the PCB, which makes it a perfect choice to slot into a white-themed gaming PC.
Performance-wise, the AORUS Pro X contains a Gen5 slot for the GPU and storage, which is fairly standard for a Z790 motherboard. However, there are a plethora of additional slots to support multiple graphics cards and storage, allowing consumers to add more parts to their build to increase performance and storage capacity.
Perhaps the main performance benefit of the Z790 Gen X motherboards over the original Z790 designs is the improvement to RAM, as these motherboards support higher overclocking speeds. With support for transfer speeds of up to 8266MHz, users can utilise every ounce of the best DDR5 RAM kits on the market, whilst also alleviating some of the stress on the CPU.
Another major benefit of the Z790 Pro X is the increase networking capabilities. With WiFi 7 and 5Gb LAN included within the rear IO, consumers have access to even faster internet compared to WiFi 6E and 2.5Gb LAN found on most of the original Z790 designs.
Whilst this design isn’t too expensive compared to Gigabyte’s previous Z790 motherboards, the improvements won’t have a significant impact on the overall performance of your PC. As a result, anyone with an existing Z790 won’t need to worry about upgrading. Also, the lack of PCI-E 5.0 on this design is slightly disappointing, as there are plenty of similarly-priced Z790 motherboards that offer better support for Gen5 components.
Pros
- Looks amazing in an all-white build.
- PCI-E 5.0 x16 and x4 slots.
- Designed for 14th-Gen CPUs.
Cons
- Very expensive.
- Durable armour casing is excessive.

2. ASUS ROG Maximus Z790 Hero
ATX
Form Factor
1x Gen3 & 3x Gen4
PCI-E x4 Slots
2x Gen5 & 1x Gen4
PCI-E x16 Slots
DDR5 7800MHz
RAM Support
The ASUS ROG Maximus Z790 Hero is a high-end motherboard that boasts a look that is associated with more traditional gaming PCs. With a darker tone across the heatsinks and PCB, accented by an array of RGB lighting, this contrasting design is perfect for gaming enthusiasts looking to show off every element of their PC. But this board isn’t all about the looks, as the Maximus Z790 Hero is packed with a healthy amount of features to provide pro gamers with everything they need.
Featuring dual PCI-E 5.0 slots for graphics cards, this motherboard is well-equipped to support optimal gaming performance for years to come. On top of this, the included ROG Hyper M.2 Card allows users to upgrade their storage to a Gen5 SSD. Whilst it would have been nice to have a PCI-E 5.0 x4 slot on the board itself, this card is a good way to work around these limitations, as most consumers are unlikely to double up on GPUs.
Throughout the rest of the motherboard, connectivity remains pretty strong. The inclusion of Thunderbolt 4 on the rear IO allows gamers to charge up wireless gaming peripherals quickly, whilst also offering unrivalled speeds for transferring data. On top of this, the support for overclocked DDR5 RAM will let gameplay remain smooth and responsive, even in the most demanding titles.
Unfortunately, the excellent feature-set and design of the Maximus Z790 Hero comes with a fairly heavy price tag. This means that the majority of builders won’t be able to afford this design, but this shouldn’t be much of an issue for anyone picking up an i9 14900K. Also, this motherboard does have some weak points, with the support for storage standing out. Whilst the ROG Hyper M.2 Card does help ease the performance restrictions, the reliance on Gen3 slots means performance will be restricted on secondary M.2 SSDs.
Pros
- Insane amount of RGB.
- Thunderbolt 4 compatibility.
- High speed RAM overclocking.
Cons
- Gen5 is only available through the included Hyper card.
- Doesn't support 10 Gigabit LAN.
- Very expensive design.

DDR5 7600MHz
RAM Support
The MSI MPG Z790 Carbon WiFi is a more affordable Z790 motherboard that still manages to provide plenty of features you’d expect to find on a high-end gaming PC. If you’re planning on spending most of your budget on a CPU, then the Z790 Carbon WiFi is the best way of ensuring you stay on track financially. On top of this, the Carbon WiFi boasts a fairly neutral design that will look great in both workstations and gaming PCs, and the ATX form factor means this design will fit into most PC cases.
In terms of performance, this motherboard comes equipped with a PCI-E 5.0 slot for both a GPU and M.2 SSD, providing users with the connectivity required to get the best out of their components for at least a few years. Plus, there is also an abundance of Gen4 slots for M.2 storage, allowing users to store an abundance of games without having to constantly move them around to different storage solutions.
The connectivity on the rear IO is also fairly strong, with multiple USB-C ports and plenty of USB 3 connections. This allows users to connect plenty of high-end peripherals and accessories, with the higher transfer speeds leading to more reactive inputs. As for networking, the choice between 2.5Gb LAN or WiFi 6E means users should receive fast and stable internet when connecting either wired and wirelessly.
Whilst the lower pricing of this board compared to the other Z790 motherboards we tested makes the Carbon WiFi a valuable option, there are a few setbacks that come with the improved affordability. For example, the lack Thunderbolt 4 on the rear IO puts this board at a disadvantage when it comes to connecting peripherals and external drives, restricting transfer speeds.
Pros
- Incredibly rich set of features, geared towards top-end builds.
- Strong VRM power phase design is perfect for overclocking.
- Minimalist black aesthetic looks great.
Cons
- One of the most expensive top-end boards.
- No 10 Gigabit LAN support.
- MSI Center software is difficult to use.
